Before this patch, only the "Coverage" mode (default) is supported. For more information, there are three pixel blend modes in DRM driver: "None", "Pre-multiplied", and "Coverage". To understand the difference between these modes, let's take a look at the following two approaches to do alpha blending: 1. Straight: dst.RGB = src.RGB * src.A + dst.RGB * (1 - src.A) This is straightforward and easy to understand, when the source layer is compositing with the destination layer, it's alpha will affect the result. This is also known as "post-multiplied", or "Coverage" mode. 2. Pre-multiplied: dst.RGB = src.RGB + dst.RGB * (1 - src.A) Since the source RGB have already multiplied its alpha, only destination RGB need to multiply it. This is the "Pre-multiplied" mode in DRM. For the "None" blend mode in DRM, it means the pixel alpha is ignored when compositing the layers, only the constant alpha for the composited layer will take effects.

Please note that position of the hardware component that is chosen as CRC generator in the display path is significant. For example, while OVL is the first module in VDOSYS0, its CRC won't be affected by the modules after it, which means effects applied by PQ, Gamma, Dither or any other components after OVL won't be calculated in CRC generation.

In OVL adaptor, there's no image procession after Mixer, unlike the OVL in VDOSYS0, Mixer's CRC will include all the effects that are applied to the frame.
